Splits each input raster into a series of tiles by specifying either a tile size or a number of tiles.
Note:Alternatively, you can use theTilertransformer. The following table compares the Tiler and the RasterTiler:
| Tiler | RasterTiler | |
|---|---|---|
| Type of data accepted | All types | 只有栅格 |
| 瓷砖尺寸单位 | 地面坐标 | 像素坐标 |
| 瓷砖行编号（0,1，......） | Bottom to top | 从上到下 |
| 支持强制平等块 | No | Yes |
| 支持栅格索引属性 | No | Yes |
| Supports number of horizontal/vertical tiles attribute | No | Yes |
参数
Tile Size or Number of Tiles
Choose how the input raster should be split.
列数，行数
这些参数指定要从栅格中取出的单元集中的子集的大小。它们不包括任何填充值。对于输入有效的输入，这些值必须大于0。
种子柱，种子排
这些参数指定了将开始的“种子”位置。也就是说，瓷砖边界将与指定的位置对齐。默认情况下，这是（0,0），含义从栅格的左上角开始。
Number of Horizontal Tiles, Number of Vertical Tiles
These parameters specify the number of tiles into which the input rasters will be split. These values must be greater than 0.
强制平等大小的瓷砖
This parameter controls behavior when the raster size is not a multiple of the requested tile size or number of tiles.
No: Tiles on the right or bottom edge of the raster may be smaller than other tiles.
Yes: All tiles will be the same size.
如果在频带上设置，则拆除光栅边缘的瓷砖将填充Nodata值;如果没有设置Nodata值，则RGB Rasters将具有添加alpha频带以识别填充区域。
例如，假设您具有大小为1000列的栅格，以及所选列块大小为256.当此选项为否时，将生成三个256列和一个图块的图块，为232列。当此选项是肯定的，将生成四个256列的图块，其中最后一个图块包含24列填充。
栅格索引属性
An attribute will be added to each output tile that identifies which raster it was created from. This index is zero-based, so all tiles created from the first input raster will have a value of 0, all tiles created from the second input raster will have a value of 1, and so on.
Tile Column Attribute, Tile Row Attribute
Attributes will be added to each output tile that identify the position of that tile in the input raster. These indices are zero-based.
Tile row 0, tile column 0 corresponds to the upper-left tile.
水平和垂直瓷砖属性的数量
Attributes will be added to each output tile that identify the number of horizontal and vertical tiles in the input raster.
Usage Notes
This transformer is unaffected by raster band and palette selection.

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click
beside the applicable parameter. For more information, seeTransformer Parameter Menu Options。
